Error message when compiling scripts

OS (e.g. Win10): Mac 10.10.5 Yosemite
PsychoPy version (e.g. 1.84.x): 1.84.2
Standard Standalone? (y/n) If not then what?: yes
What are you trying to achieve?: Trying to build and execute a program for a class

What did you try to make it work?: updated my operating system, install a new version of Python, restart my computer, uninstall and reinstall Python.

What specifically went wrong when you tried that?:
OSError: dlopen(c, 6): no suitable image found. Did find:
/usr/local/lib/c: stat() failed with errno=13

I have been trying to get PsychoPy to run on my computer for over a month. The scripts I create work fine on other computers that I have access to, which have the same version of Python, but a different OS (They have OSX El Capitan 10.11.6).

Also when I first download PsychoPy on my computer nothing pops up to run diagnostics, but when I open it for the first time on other computers a gray screen pops up and it seems as though PsychoPy is testing animations or something alone those lines. Is this related to why I am having trouble compiling and running scripts?

From that level of information I’m afraid I have no real idea. I use OSX 10.10 all the time. I assume you’re using the standalone installer.

This is just because that only runs the first time you as a user run the application. Re-installing doesn’t get rid of the user settings. You could try removing the user prefs and application data as well. These are in a “hidden” folder called .psychopy in your home folder. You could go to the terminal and do rm -R ~/.psychopy2 to get rid of them and try restarting psychopy
